Pleural empyema is a severe condition associated with high morbidity and mortality. Treatment usually consists of pleural drainage with chest tube or surgery, in combination with antimicrobial treatment. Severe pneumonia can evolve in a necrotizing pneumonia, given a higher susceptibility to the occurrence of bronchopleural fistulas with persistent air leaks. This complicates recovery, and surgery may not always be the optimal treatment. We present a case involving a 17‐year‐old female patient who experienced a post‐operative persistent air leak due to necrotizing pneumonia after video‐assisted thoracic surgery decortication for empyema, which was successfully treated using an endobronchial valve. After 6 months the valve was removed without complications. Follow‐up imaging and lung function revealed a limited area of atelectasis and minimal pleural thickening with normal lung volumes.

The bronchopleural fistula (BPF) is a pathological communication between the bronchus and the pleural space. Diagnosing BPF poses a significant challenge for physicians, particularly when identifying multifocal BPFs. Traditionally, retrograde instillation of methylene blue (MB) into the pleural cavity with simultaneous observation with a bronchoscope has been used to locate a BPF. However, MB instillation is not effective in identifying multifocal BPFs. In this article, we report a new method for locating multifocal BPFs which involves placing the endobronchial valve (EBV) in reverse combined with retrograde MB instillation. First, the thoracic cavity is filled with MB solution. Then, using bronchoscopy, the location of a BPF can be identified as the MB solution flows into the bronchus. Secondly, an EBV is deployed in reverse in the bronchus where the identified BPF is located. Retrograde MB instillation is then repeated to locate any additional BPFs until no new ones are found. Two cases were reported using this novel method to identify multifocal BPFs, and each case was ultimately diagnosed with 2 BPFs. After precisely locating all the BPFs, the EBVs are then removed and placed forward in the target bronchi for treating the BPFs. During the follow‐up period, no recurrence of BPFs was observed. We conclude that reversed placement of EBVs combined with retrograde MB instillation appears to be an effective approach for locating multifocal BPFs. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Pneumothorax and bronchopleural fistula (BPF) are potentially fatal complications that can occur in patients with COVID‐19 pneumonia. Early detection, appropriate treatment, and consideration of surgical intervention are necessary for optimum outcomes. Introduction: Healthcare professionals face complex challenges as a result of the rare emergence of pneumothorax among the variety of COVID‐19 complications, including severe viral pneumonia. Case History: A 57‐year‐old male with multiple comorbidities diagnosed with COVID‐19 pneumonia was admitted to our center and exhibited bilateral crepitations. During hospitalization, the patient developed right‐sided pneumothorax that persisted despite chest tube insertion was linked to the presence of BPF. Discussion: The occurrence of pneumothorax in COVID‐19 patients is relatively rare risk factors for which are not yet fully understood, although smoking history may play a role. Conservative management is recommended for asymptomatic cases, while intercostal drainage is necessary for symptomatic patients. Surgical intervention may be required to manage the BPF in some instances. Conclusion: Pneumothorax and BPF are rare but potentially life‐threatening complications in patients recovering from COVID‐19 pneumonia. Early recognition, appropriate treatment, and consideration of surgical intervention are crucial for optimizing patient outcomes. [ABSTRACT FROM AUTHOR]

Bronchopleural fistulas are rare complications of bevacizumab treatment. Herein, we report a case of bronchopleural fistula after bevacizumab therapy. The patient was a 65‐year‐old man with lung cancer who underwent a right lower lobectomy with systemic lymph node dissection after induction chemotherapy with bevacizumab. Pathological examination revealed no residual tumor cells in the resected specimen. The patient presented with severe dyspnea on postoperative day 26. Bronchoscopy revealed a bronchopleural fistula in the membranous portion of the right intermediate bronchus; the bronchial stump remained intact. The bronchopleural fistula was repaired with muscle flaps, and bronchoscopy 9 months after surgery showed satisfactory healing of the fistula. The patient has been alive for 5 years without evidence of recurrence. Careful attention must be paid to postoperative management when bevacizumab is used for induction therapy.

Chronic post‐pneumonectomy empyema (CPPE) associated with bronchopleural fistula (BPF) is a potentially fatal complication and remains a surgical challenge. This study aims to propose a treatment protocol for managing this severe disease. From July 2009 to June 2021, 47 CPPE with BPF patients were treated in our department. CT scan with 3D reconstruction was used to detect BPF and to evaluate the location and volume of empyema cavity. Different surgical techniques were used to close BPFs according to they sizes. Multiple pedicled muscle flaps were chosen to fill the empyema cavity, and among them, latissimus dorsi (LD) was the mostly used flap. For cases that regional flaps were not suitable, free flaps were used. Patients were followed‐up from 7.9 to 102.8 months. Forty‐four patients (93.6%) healed after the operation. Closure of BPFs failed in three patients (6.4%), leading to regional infection. These patients were treated by bronchoscopic application of sealants, continuous drainage and antibiotics, and they eventually healed. Total or partial flap loss was not seen in any of the cases. Treatment protocol was proposed based on these results. CT scan with 3D reconstruction is an effective examination to evaluate pleural cavity defect and BPF. Proper technique to close the BPF and right choice of flap to fulfil the empyema cavity are the two most important key points to treat CPPE associated with BPF patients. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to investigate the results of postoperative bronchopleural fistula repair and to identify adverse factors for its success. Methods: We retrospectively reviewed the surgical results of 39 patients who underwent surgical repair for postoperative bronchopleural fistula between January 2010 and June 2020. Success of bronchopleural fistula repair was defined as the visual closure of the bronchopleural fistula with the absence of an air leak, a recurrence of bronchopleural fistula and infection in the thoracic cavity. Results: Twenty‐five (64.1%) bronchopleural fistulas occurred after pulmonary resection and 14 (35.9%) after lung transplantation. Bronchopleural fistula was diagnosed 19 days (median) and repaired 28 days (median) after the initial operation by primary closure in 27 (69.2%) patients, and by additional resection in 12 (30.8%) patients. The overall success rate was 59% (23/39) and the overall mortality was 56.4% (22/39). Multivariable analysis revealed that the patients who were supported by mechanical ventilation at the time of repair had significantly lower success rates than those without (15.4%, 2/13 vs. 80.8%, 21/26, respectively, p < 0.001). The omental flap group tended to have a better success rate than the muscle flap group (p = 0.07). Conclusions: There was a high overall mortality rate after bronchopleural fistula repair and a low success rate. Mechanical ventilation at the time of bronchopleural fistula repair was significantly related to the failure of bronchopleural fistula repair. [ABSTRACT FROM AUTHOR]

Key message: Hydropneumothorax following lobectomy or pneumonectomy is relatively uncommon, with an incidence of 1%–5%. It involves air and fluid in the pleural cavity, often due to intraoperative injury, infection, bronchopleural fistula, or mechanical ventilation. Careful management, including drainage and addressing the underlying cause, is essential to prevent serious outcomes. [ABSTRACT FROM AUTHOR]

Although pneumothorax is a well‐known complication of COVID‐19 pneumonia especially in patients requiring mechanical ventilation, bronchopleural fistula causing persistent pneumothorax in sole COVID‐19 pneumonia is extremely rare. In this case, we illustrate that bronchopleural fistula can be found in COVID‐19 pneumonia, even with no risk factors nor mechanical ventilation administration. [ABSTRACT FROM AUTHOR]

Anatomical segment‐based or subsegmental resection for early lung cancer surgery has been used in selected cases, although postoperative complications of bronchopleural fistula sometimes occur. Persistent air leaks can cause complications such as empyema and aspiration pneumonia, resulting in prolonged patient hospitalization. The traditional treatment for postoperative bronchopleural fistula is reoperation, but the advent of bronchoscopic interventional therapy usually prevents patients from needing a second operation. This article details a case of thoracoscopic segmentectomy of the left lower lung dorsal segment resulting in residual subsegmental pleural fistula, and because the use of pleural adhesives made the patient's fistula inappropriate for surgical repair, we finally used bronchoscopic injury of the airway mucosa combined with an absorbable gelatin sponge and an autologous blood closure method for successful treatment.

We report the case of a 53-year-old male that presented to our hospital with a history of a brain tumour. He was hospitalized 10 days prior in another hospital. Before surgery, he complained of mild cough. Routine chest radiography demonstrated right upper lobe consolidation which was diagnosed as hospital-acquired pneumonia. Broad-spectrum empirical antimicrobial was initiated. After surgery, his clinical condition deteriorated and he felt breathlessness. Chest radiography and computed tomography (CT) scan without contrast revealed necrotizing and cavitating pneumonia complicated by bronchopleural fistula (BPF) and hydropneumothorax. Sputum culture revealed infection of multidrug-resistant Acinetobacter baumannii (MDRAB). Despite optimal antibiotic therapy, BPF and hydropneumothorax failed to resolve and surgical approach was performed to debride the necrotic area and seal the fistula. After a month in the hospital, he was discharged and the serial chest X-ray showed good recovery of the lung. [ABSTRACT FROM AUTHOR]

Bronchopleural fistula (BPF) can complicate necrotizing pneumonia. Surgery would be indicated in patients who fail conservative management, yet this group is often of poor pulmonary function and general condition. Bronchial occlusion with endobronchial Watanabe spigots (EWS) can be a potential alternative treatment when the culprit bronchi can be isolated. In this case report, we describe a middle-aged gentleman who presented with necrotizing pneumonia complicated with pyopneumothorax with right upper lobe BPF, and who had failed to respond to chest drainage and antibiotics. EWS bronchial occlusion finally led to cessation of air leak, allowing removal of chest tube. EWS were removed uneventfully six months later. This case highlights the role of EWS in the management of BPF in patients with high surgical risk. [ABSTRACT FROM AUTHOR]

COVID‐19 pneumonia causes several complications that include pneumothorax, hydropneumothorax, empyema, and rarely leads to bronchopleural fistula (BPF). BPF is a communication between the pleural space and the bronchial tree. We report a case of 24 years man with pneumothorax, hydropneumothorax, and BPF that appeared after COVID‐19 infection.

Introduction: A refractory bronchopleural fistula leading to respiratory failure in a trauma patient is one of the most challenging pathologies to manage in one of the most challenging patient populations. Modern equipment and techniques have decreased and perhaps even eliminated the need for anticoagulation with ECMO, and it is finding an important niche in saving this patient population from refractory hypoxia. We review here our experience with three refractory traumatic bronchopleural fistulae utilizing venovenous ECMO as the primary treatment modality.Material and Methods: Retrospective chart review of three cases of refractory traumatic bronchopleural fistula treated primarily with ECMO and an ultra-lung protective strategy.Results: The use of an ultra-lung protective strategy with ECMO allowed sealing of all three bronchopleural fistula.Conclusions: Traumatic bronchopleural fistulae require careful thought and early utilization of lung protective strategies to facilitate healing of the injured lung.

Background: The bronchopleural fistula (BPF) is a rare but potentially fatal complication of major thoracic surgery. The purpose of this work is to investigate the risk factors associated with the development of fistulas after lobectomy and pneumonectomy. Methods: We retrospectively reviewed the records of 835 patients who underwent major anatomic lung resection at our centre from January 2003 to December 2013. Of these, 49 underwent pneumonectomy (P group) and 786 lobectomy (L group). Results: A total of 18 patients (2.6%) developed a BPF in the postoperative period, of which there were 11 in the L group (1.3%) and seven in the P group (14.28%). The 30‐day mortality was 0.05% (one patient after right pneumonectomy). In the L group, three patients developed a fistula after a left lobectomy and eight after a right one, of which four developed after bilobectomy. Univariate analysis showed that induction therapy, lower lobectomy, manual suture of the bronchus, ‘not covered’ bronchial stump, empyema, postoperative anaemia and pulmonary infections and mechanical ventilation >24 h are associated with the development of fistulas after lobectomy. Multivariate analysis confirmed that induction therapy, manual closure of the bronchus, postoperative pulmonary infections and anaemia are the main risk factors involved in our series. In the P group, four patients developed a fistula after a right pneumonectomy and three after a left one. Postoperative empyema and pulmonary infections, mechanical ventilation >24 h and female gender emerged as the main risk factors on univariate analysis, while on multivariate analysis, only the female gender presented a trend towards significance. Conclusions: Postoperative pulmonary infections, empyema and mechanical ventilation >24 h are strongly associated with the development of BPFs after both pneumonectomy and lobectomy in our series.

Bronchopleural fistula with subsequent hydropneumothorax is an important complication of necrotizing pneumonia. Chest X‐ray is an excellent diagnostic tool which can suggest hydropneumothorax. When present, this requires admission for drainage. If discharged after necrotizing pneumonia, follow‐up should include a chest X‐ray to rule out this complication. [ABSTRACT FROM AUTHOR]

Key Clinical Message Spontaneous pneumothorax following radiotherapy for pulmonary malignancy is an unusual clinical condition. Here, we report a case of a 78-year-old male suffering from dyspnea during radiotherapy for squamous cell lung cancer of the right main bronchus. Imaging studies and fiberoptic bronchoscopy revealed that pneumothorax was due to a bronchopleural fistula. [ABSTRACT FROM AUTHOR]

Liposome-encapsulated hemoglobin ( LEH) has been reported to accelerate wound healing in the stomach and skin in an experimental setting. LEH was tested in bronchial anastomotic healing after radiation and pneumonectomy in the rat. Sprague- Dawley rats ( n = 61) received preoperative radiation (20 Gy) to the chest and underwent left pneumonectomy with bronchial stump closure using the Sweet method 4 days later, when they were randomized to receive intravenous infusion of LEH with high O2 affinity ( P50 O2 = 17 mm Hg, 10 mL/kg, n = 32) or saline ( n = 29). Additional rats ( n = 18) were treated in the same way without preoperative radiation. Bronchial anastomotic healing was evaluated 2 days after surgery by determining the bursting pressure and infiltration of neutrophils, monocytes, and macrophages. Bronchial bursting pressure was elevated in the rats receiving LEH both in the unirradiated group ( LEH 212 ± 78 vs. saline 135 ± 63 mm Hg, P < 0.05) and in rats with preoperative radiation ( LEH 162 ± 48 vs. saline 116 ± 56 mm Hg, P < 0.01). Moreover, the percentage of rats with bursting pressure <100 mm Hg tended to be smaller in the unirradiated group ( LEH 1/9 [11.1%] vs. saline 4/9 [44.4%], NS) and was significantly reduced in irradiated animals ( LEH 3/32 [9.4%] vs. saline 11/29 [38%], P < 0.05). There were no morphological differences except for macrophage infiltration to the anastomotic area, which was significantly prominent in the LEH-treated rats ( P < 0.05) regardless of the presence or absence of preoperative irradiation ( IR). The results suggest that LEH with high O2 affinity may improve mechanical strength and morphological findings in bronchial anastomosis in rats regardless of the presence or absence of preoperative IR. The irradiated rats later treated with LEH had equivalent or better bronchial healing than that of saline-treated naïve animals undergoing pneumonectomy alone. [ABSTRACT FROM AUTHOR]

Background: Bronchopleural fistula is an especially severe complication with a high mortality rate. We investigated the efficiency of our surgical treatments for this severe complication. Methods: From January 2007 to December 2009, standard surgical resections and systematic lymph node dissections for non-small cell lung cancer (NSCLC) were performed on 1178 patients at our institution. Eight patients developed bronchopleural fistulas during the postoperative follow-up period, and received reoperations. Seven patients underwent additional pneumonectomies, and the omental flap, which was mobilized using a transdiaphragmatic harvesting technique through the usual thoracotomy, was used to cover postpneumonectomy bronchial stump. The other patient, who had received right side pneumonectomy and systemic lymph node dissection, received omental flap stuffing and covering without reclosure of the stump or carinal plasty. Results: Bronchopleural fistulas after standard surgical resections and systematic lymph node dissections for NSCLC were observed in eight patients (0.68%) in our study. The period between pulmonary resection and the appearance of bronchopleural fistula ranged from eight to 19 days (median 11 days). Repairing of the bronchial fistula was successful in all eight patients and no development of late fistula was found during the follow-up period. Postoperative hospital stay for undergoing omentoplasty to repair the bronchial fistula ranged between 11 and 23 days (median 15 days). There were no complications related to the omentoplasty procedure. Conclusion: Transdiaphragmatic harvesting technique of omental flap through a thoracotomy is safe and technically feasible. Surgical treatment for postoperative bronchopleural fistula with omental flap covering is effective. [ABSTRACT FROM AUTHOR]

A 68-year-old woman with interstitial lung disease related to dermatomyositis and systemic scleroderma was admitted to our hospital with fever and dyspnoea. Although the fever was reduced after antibiotic therapy, a left pneumothorax suddenly occurred on day 27 after admission. A continuous air leak persisted despite chest drainage with three tubes and repeated pleurodesis. Chest computed tomography (CT) images showed a cavitary lesion with a pinhole in the left upper division, which was suspected to be the affected lesion with the air leak. Virtual bronchoscopic navigation images were constructed from CT data. Bronchial occlusion with Endobronchial Watanabe Spigots (EWSs) was performed on day 52. Two medium-sized EWSs were inserted into the left B1+2a and B1+2b, and the air leak stopped immediately. No procedure-related adverse events occurred. All three chest tubes were successfully removed by day 60. This case demonstrates that virtual bronchoscopic navigation can improve bronchial occlusion procedures using EWSs. [ABSTRACT FROM AUTHOR]

SummaryThe anaesthetic management of a left pneumonectomy in a 18-month-old girl with a bronchopleural fistula is described. An ordinary tracheal tube was slit at the bevel to ensure upper lobe ventilation on right endobronchial intubation. A combination of a bronchial blocker, endobronchial intubation with a slit tube, and nerve blocks for these manoeuvres was used. Pain relief by a thoracic epidural block ensured good physiotherapy and a comfortable postoperative period. [ABSTRACT FROM AUTHOR]

Summary: A bronchopleural fistula (BPF) consists of a direct communication between the bronchial tree and the pleural space, which can develop secondary to (pleuro) pneumonia. Thoracotomy has been reported as a viable treatment option in cases of nonresponsive pleuropneumonia, pleural abscess formation and necrotising pneumonia. The presence of a BPF can delay and even prevent healing of the thoracotomy site, with clinical signs of coughing and putrid purulent nasal discharge often seen. In this case report, we describe the diagnosis and localisation of a bronchopleural fistula using retrograde instillation of methylene blue through the thoracotomy site, followed by the successful closure of the BPF using endoscopic application of acrylate co‐monomer glue (Glubran 2®).

Thoracotomy patch leads used for implantable cardioverter defibrillators (ICDs) are generally safe and effective. We describe two patients in whom a late complication of patch lead migration occurred years after the original implants, causing a bronchopleural fistula in one and lingular lobe collapse in the other patient. We conclude that patch migration is a late but possible complication of extrapericardial ICD leads, and should be suspected in patients who present with hemoptysis, atypical pneumonia, or lung collapse after the initial ICD surgery.

A 72‐year‐old Japanese man who had undergone resection of a left upper lung carcinoma developed chronic empyema with bronchopleural fistula and destroyed lung 12 years after surgery. Open‐window thoracotomy and bronchial occlusion with an endoscopic Watanabe spigot (EWS) were performed to control infection. However, the EWS was easily dislodged due to remarkable bronchial deformation, and he experienced repeated episodes of pneumonia. We performed extensive bronchial filling with N‐butyl‐2‐cyanoacrylate. Stable occlusion was achieved, and there was no recurrence of pneumonia. N‐butyl‐2‐cyanoacrylate was a useful embolic agent because it moulded to the shape of the tracheal lumen and remained in place. [ABSTRACT FROM AUTHOR]
